洞庭湖水位，直接影响到湖泊面积、容积等的变化，加剧水患危机，并由此引发严重的洪涝灾害。本文通过大量遥感成果的分析总结，建立了洞庭湖湖泊面积、容积与水位关系及蓄洪调节评估数学模型。
The water level in Dongting Lake directly affects the change of lake area and volume, exacerbating the flood crisis and causing serious floods. Based on the analysis and summary of a large number of remote sensing results, the paper establishes the relationship between the area of Dongting Lake, the relationship between volume and water level, and the mathematic model of flood regulation and adjustment.
